Iteron Plasmids

open access: yesMicrobiology Spectrum, 2014
ABSTRACT Iteron-containing plasmids are model systems for studying the metabolism of extrachromosomal genetic elements in bacterial cells. Here we describe the current knowledge and understanding of the structure of iteron-containing replicons, the structure of the iteron plasmid encoded replication initiation proteins, and the molecular ...

Plasmid Negative Regulation of CPAF Expression Is Pgp4 Independent and Restricted to Invasive Chlamydia trachomatis Biovars

open access: yesmBio, 2018
Chlamydia trachomatis is an obligate intracellular bacterial pathogen that causes blinding trachoma and sexually transmitted disease. C. trachomatis isolates are classified into 2 biovars—lymphogranuloma venereum (LGV) and trachoma—which are ...

Co-occurrence of blaNDM–1 and mcr-9 in a Conjugative IncHI2/HI2A Plasmid From a Bloodstream Infection-Causing Carbapenem-Resistant Klebsiella pneumoniae

open access: yesFrontiers in Microbiology, 2021
Spread of the carbapenemase-encoding and mobilized colistin resistance (mcr) genes among Enterobacteriales poses a great threat to global public health, especially when the both genes are transferred by a single plasmid.

A certified plasmid reference material for the standardisation of BCR-ABL1 mRNA quantification by real time quantitative PCR [PDF]

open access: yes, 2015
Serial quantification of BCR–ABL1 mRNA is an important therapeutic indicator in chronic myeloid leukaemia, but there is a substantial variation in results reported by different laboratories.

Two Different Tetracycline Resistance Mechanisms, Plasmid-Carried tet(L) and Chromosomally Located Transposon-Associated tet(M), Coexist in Lactobacillus sakei Rits 9 [PDF]

open access: yes, 2008
Lactobacillus sakei is extensively used as functional starter culture in fermented meat products. One of the safety criteria of a starter culture is the absence of potentially transferable antibiotic resistance determinants.

The role of hosts, plasmids and environment in determining plasmid transfer rates: a meta-analysis [PDF]

open access: yes, 2019
Plasmids transfer at highly variable rates which spread over 10 orders of magnitude. While rates have been measured for decades and it is known that the rates are affected by biotic and abiotic factors, it is unclear how and to what extent these factors ...

Genome characteristics of the optrA-positive Clostridium perfringens strain QHY-2 carrying a novel plasmid type

open access: yesmSystems, 2023
Clostridium perfringens is a bacterial species of importance to both public and animal health. The gene optrA is the first gene that confers resistance to the tedizolid, a last-resort antimicrobial agent in human medicine.

Limited Genetic Diversity of blaCMY-2-Containing IncI1-pST12 Plasmids from Enterobacteriaceae of Human and Broiler Chicken Origin in The Netherlands

open access: yesMicroorganisms, 2020
Distinguishing epidemiologically related and unrelated plasmids is essential to confirm plasmid transmission. We compared IncI1–pST12 plasmids from both human and livestock origin and explored the degree of sequence similarity between plasmids from ...

Comparative genomic analysis of two novel plasmids from Acidithiobacillus ferrivorans strain PQ33

open access: yesRevista Peruana de Biología, 2021
Acidithiobacillus ferrivorans is a psychrotolerant acidophile capable of growing and oxidizing ferrous and sulphide substrates at low temperatures. To date, six genomes of this organism have been characterized; however, evidence of a plasmid in this ...

Molecular Characterization and Comparative Genomics of IncQ-3 Plasmids Conferring Resistance to Various Antibiotics Isolated from a Wastewater Treatment Plant in Warsaw (Poland)

open access: yesAntibiotics, 2020
As small, mobilizable replicons with a broad host range, IncQ plasmids are widely distributed among clinical and environmental bacteria. They carry antibiotic resistance genes, and it has been shown that they confer resistance to β-lactams ...
